Joe_Carrick Posted February 8, 2017 Share Posted February 8, 2017 Should chases and other furred areas be considered a part of "Living Area"? Normally, I would just make the walls around such spaces "No Room Definition" so that they would be counted as a part of the larger room. However, this creates a problem with the "Room Interior Elevations" ignoring those walls - except where they intersect with other walls. How do you handle this conundrum?

rlackore Posted February 8, 2017 Share Posted February 8, 2017 I try to follow the ANSI Z765 standard, which includes interior chases/etc. as Finished Area, eg Living Area. Link to comment Share on other sites More sharing options...

DRAWZILLA Posted February 8, 2017 Share Posted February 8, 2017 I just make them a closet and re-name to Void 1,2,3,4, so it's included b/c someone has to build it ,and I charge by the square foot. Link to comment Share on other sites More sharing options...
Korel_Design Posted February 8, 2017 Share Posted February 8, 2017 This question falls back on the appraiser. And the answer is a BIG yes indeed. First there is foundation below and roof above, so why shouldn't it be counted. If the Chase is adjacent to the Garage but surrounded on 2 or 3 sides by living area, I might include it in the Garage Area. Especially if I'm fighting tooth and nail to keep the area a specific size. All this being said, I do not use the Room Definitions to total my areas. I create a 3D Slab and stretch and shape it to cover the area I want then query it's coverage. That's how I calculate my square footage. Link to comment Share on other sites More sharing options...
RL-inc Posted February 8, 2017 Share Posted February 8, 2017 Agreed with include in Living area- and so does my building department. Both floors of a stairwell also. Link to comment Share on other sites More sharing options...
Joe_Carrick Posted February 8, 2017 Author Share Posted February 8, 2017 OK, so the key is to just not include in the Schedule. 2 hours ago, RL-inc said: Both floors of a stairwell also. Really? That's not correct any place I know of. 4 hours ago, dshall said: It is heated area. Not by my way of thinking. It's just dead space. Link to comment Share on other sites More sharing options...

It's really only "dead space" if you truly isolate those areas by placing them outside the building envelope. Link to comment Share on other sites More sharing options...

Not by my way of thinking. It's just dead space. Really? You do not include duct chases in the heated floor area? Wow. The city and everybody else has been doing it wrong for 30 plus years. And yes, the stairwell is always counted twice. Not only for floor area (truly a bit of gray area here) but also for FAR. With that being said, I have been known to be wrong quite often.

Joe_Carrick Posted February 8, 2017 Author Share Posted February 8, 2017 Heated Floor area (aka Conditioned Space) is Interior area (not Living Area) and the Ceiling Heights are important to calculate the volume. From the standpoint of sizing an HVAC system the Volume is what's important, not Floor Area. 9 minutes ago, dshall said: You do not include duct chases in the heated floor area? Would you count an Attic as heated space just because there are ducts in the Attic? Sometimes the furred areas are just for Plumbing or just to enclose a structural element like a Steel Column. There are a lot of things to consider when determining what is Living Area, what is Conditioned and what is neither. Link to comment Share on other sites More sharing options...

I was just trying to share my experience with the city of San Diego over the last 37 years and thousands of jobs. Would I count the attic as heated space because there are ducts in the attic? Is that a serious question? 1 Link to comment Share on other sites More sharing options...
Joe_Carrick Posted February 8, 2017 Author Share Posted February 8, 2017 Here are some excerpts from Wikipedia: Floor area ratio (FAR) is the ratio of a building's total floor area (zoning floor area) to the size of the piece of land upon which it is built. The terms can also refer to limits imposed on such a ratio. As a formula: Floor area ratio = (total amount of usable floor area that a building has, zoning floor area) / (area of the plot) Common exclusions to the total calculation of square footage for the purpose of floor area ratio (FAR) include unoccupied areas such as mechanical equipment floors, basements, stair towers, elevator shafts, and parking garages. From Investopedia: What is the 'Floor Area Ratio - FAR' The floor area ratio (FAR) is the relationship between the total amount of usable floor area that a building has, or has been permitted for the building, and the total area of the lot on which the building stands.

RL-inc Posted February 8, 2017 Share Posted February 8, 2017 It seems odd that there is not a uniform definition for what should be included in living space. Here in Bend, I have had accessory dwelling unit additions where the size allowed by the planning department was based on a percentage of the "Living Space" of the main dwelling. When I asked how we were defining "Living Space" they told me that was based on the building departments interpretation. The building department has no definition of "Living Space" nor is there one in the Oregon structural code. ( There is a definition of conditioned space however. ) In regards to the stairwell area being counted on both floors, the plan intake department here only started requiring this about 2 years ago. In Portland I have had to include all floors for quite some time. I have also had appraisers only calculate the floor area that the stair system started on and not the open area above. (2 story structure only) The builder and realtor have had some issue with the total living area sq.ft. difference from what I am showing on the plans and what the appraiser says is on site but I have to go back to what he local building department requires to issue a permit and what they will turn in to the assessors office.

As I said, you win. BTW, here is an easy rebuttal..... wikipedia does not count parking garages?.... do you really believe the city will not count a parking garage as floor area for FAR. BTW, is that a parking garage that has only one wall open or 3 walls open or 70% of wall area open..... does it matter? Joe, you surprise me, I thought you would of known how the City of San Diego determines what areas to use for FAR. But you are the Architect and I am a lowly designer.

Is it the builder? Is it the health department? Link to comment Share on other sites More sharing options...
Alaskan_Son Posted February 8, 2017 Share Posted February 8, 2017 What the heck just happened? We went from talking about what we included as Living Area to the definitions of and local requirements for figuring FAR. Not the same thing and may even use 2 different sets of criteria in many cases. Link to comment Share on other sites More sharing options...
